I’m going thru the online zope book (2.6) and trying out the simple interest rate calculator web application under the section:

Creating a Basic Zope Application Using Page Templates and Scripts

http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/BasicObject.stx

I’ll attach the error log:

Does this indicate an error with my python script?
